230.7 (SRP 2.5.2.6) 231.18 (SRP 2.5.1 I, III)

On page 2.5-21 of Section 2.5.1.1.3, there is a brief discussion of post-glacial structural features such as "pop-ups" and minor fault displacements which attributes these to glacial unloading.

There is no attempt to relate these to possible seismicity.

There

have, however, been earthquakes attributed to crustal unloading (Pomeroy et al, 1976; YerKes et al, 1983).

Please discuss the significance of this to the Nine Nile Point site.

Ihclude in the discussion estimates

.of...the size, of possible events and the vibratory ground motion they might produce at the site.

Demster Zone:

(SRP 2.5.1 - I, III) a)

Inasmuch as complex folding and fracturing indicative of high stress. concentration is inconsistent with a series of broad open folds, please explain how spacing and alignment of the structure contour pattern indicate folding, rather than faulting, is the dominant

process, as stated on p. 2.5-83.

b)

What information precludes the possibility of the Demster Fault Zone from having primarily left-lateral strike-slip displacement with a minor dip slip component?

There are indications on the structure contour map (Fig. 2-4 of Appendix 2I) of a large left-lateral offset.

c)

The structure contour map, Fig. 2-9 of the Demster Fault study (Appendix 2I), on top of the Oswego, has boring locations which differ from the structure contour map of the referenced NYSEG

'PSAR Section 2.5 Fig. 2.5-14 on top of the Pulaski shale of the proposed New Haven site.

Specifically, R6 on Fig. 2-9 (Appendix 2I) is R16 of Fig. 2.5-14; R13 on Fig 2-9 is R15 on Fig. 2.5-14; R15 on Fig. 2-9 is R13.

Please determine which are the correct boring locations and so indicate on another map.

l%

\\

d)

Please provide a description of the criteria used to determine the top of Zone 1 of the Oswego Sandstone in developing the data for the structure contours of Fig. 2.4 of Appendix 2I.

Specifically; core logs of Appendix 2C of the referenced PSAR for the New Haven site indicate.interpreted formation and zonal contacts.

The contact at top of Zone 1 in different core logs do not appear to be consistent.

Also, assuming R13 of Fig. 2-9 is actually R15, the contours bounding the boring location is off by 10 feet or one contour

- interval.

e) lJhat information justifies bringing the structure contours.into parallelism with the Demster Fault Zone?

The sparse boring locations in the area do not appear to require such an interpretation.
